An Overlooked Class of Large-Scale CMB Features: Mirror-Reversed Structures with Opposite Physical Properties Why Big Bang, Inflation, and Other Predominantly Scalar-Driven Frameworks Struggle, and How Tensorial Internal Dynamics (MDD) Can Naturally

Observations of the cosmic microwave background (CMB) have revealed a range of large-scale features that remain in tension with standard assumptions of statistical isotropy and Gaussian randomness. While such features are often treated as statistical anomalies, this work argues that a subset of these observations represents a distinct and previously under classified class of structures. These structures exhibit mirror-reversed correspondence accompanied by systematically opposite physical properties, including phase inversion, parity-opposed polarization, and apparent handedness reversal. We argue that existing Big Bang, inflationary, and other predominantly scalar-driven cosmological frameworks struggle to accommodate this class of features in a natural and non–fine-tuned manner, due to the absence of internal mechanisms enforcing orientation- and phase-reversing correspondence at cosmological scales. This work proposes a new morphological classification and presents a conceptual framework—Minimal Dissipation Dual (MDD)—in which intrinsic tensorial internal dynamics, driven by bi-directional torsion flows (±τ), provide a coherent geometric basis for the emergence of such structures. This paper is intended as an observational and classificatory contribution, aiming to refine how large-scale CMB features are interpreted and to motivate future theoretical developments grounded in first principles
